PRO Sennheiser IE 100 PRO WIRELESS CLEAR In Ear Dynamic Monitoring Headphones

the iems sound fairly good. But the bluetooth adapter lacks of sound quality and power, and is noisy af. The mic from the adapter is bas quality aswell buy just the iem s and a third party bluetooth adapter like fiio. That s my advice, waste pf money from my part.

Stopped working after 9 days of use. After 17 years of exclusively using Sennheiser headphones, I think it’s time to finally part ways. Goodbye Sennheiser

Basic in ear headset. Bluetooth version 5 is very old which makes it unable to use on two devices simultaneously. No supporting app for equaliser customisation. It supports high resolution codes but the ear piece is basic which can only produce mid and high the low or bass is very poor or unable to hear from it. The vocal sound is clear such as voices. The passive noice cancellation is good. For music listening it's not recommended.

The Bluetooth module quality is bad, it started with fails before 2 months using it, know it doesn't works.

Ich habe mich schon an deutlich teureren In-Ears abgearbeitet, die mich letztlich immer enttäuscht haben. Die Pro IE 100 Pro haben mich hingegen vom Sound und Tragekomfort überzeugt. Ich nutze sie auch gerne beim Radfahren. Abzug gibt es für die wenig intuitive Bedienung und die fehlende App. Es gibt keine Anzeige oder Abfrage für den Ladezustand, sondern nur eine Warnmeldung, bevor kurz danach Schluss ist.

A pesar de ser de precio elevado, el sonido y la calidad del audio es superior a cualquier producto de la competencia dentro de la gama(gama de entrada). El módulo bt es una buena solución para escuchar secuencias y metrónomo para gigs pequeños y funciona súper bien. Comparado con Shure o KZ es sin duda una muy buena inversión en esta gama de productos. Actualización: El auricular izquierdo ya no funciona...Casi no los usaba para trabajar en su mayoría eran ensayos y con el módulo BT me era suficiente. Así que el cable lo usé aproximadamente una vez por mes. A la fecha no más de 10 ocasiones. Primero el auricular izquierdo comenzó con un falso contacto. Y después de dos o tres cambios más dejo de escucharse. Se que es el auricular por qué he probado el auricular derecho con las diferentes entradas tanto del módulo como del cable y sigue funcionando perfectamente.

Buen producto

Sound quality: neutral sound, a bit on higher side. Low is very good and clear. Sound signature is really of my taste. Crystal clear, crisp, on point sound. Most noticeable attribute is sound stage. Very wide spacious sound stage. Build quality: very comfortable and light. Best fit in ear. But feels delicate specially on the point of connectors. Connector: the connector is not typical ‘MMCX’ type. It is Sennheiser exclusive connector. This is the only drawback i have found. A universal connector helps in having choices over buying different quality and of different length of cable. Though the cable quality is very good. Soft and durable. Bluetooth connector: Bluetooth connector is just for casual listening. I noticed a huge difference in sound stage while shifting from wired to Bluetooth connector. With Bluetooth connector it sounds just like any other Bluetooth earbuds half the price. So I never use Bluetooth. It is just for ‘just in case’ type of purpose. Overall I found it to be really good sounding and best fit among all other earphones in my collection. I have bought it in 8.7k with Bluetooth adapter which is a great deal. ** The wireless version is not just wireless. It comes with both 'Bluetooth adapter' and '3.5mm cable'. So wireless version is basically the wired version along with an additional Bluetooth adapter. See the box contains in my uploaded picture.

What I liked about these is that you have the option to go wired or wireless which gives the best of both worlds. The sound quality is good for what I use it for (mostly music, podcasts) and they are pretty good at noise cancelling to an extent. It seems like the trend is going towards Bluetooth headphones so having the option to go wired is nice.
